DC4 crosslinker, an 18Å mass spectrometry-cleavable crosslinking reagent, features two intrinsic positive charges facilitating the fragmentation of cross-linked peptides into their constituent peptides through collision-induced dissociation or in-source decay. Initial fragmentation leads to cleavage adjacent to the positive charges, enabling the identification of cross-linked peptides as pairs of ions with precise mass separation. Furthermore, the resultant intact peptide fragments can undergo further fragmentation, producing a sequence of b- and y-ions for peptide identification.
The IC50s of DC4SMe on Ramos, Namalwa and HL60 s cancer cells were 1.9 nM, 2.9 nM and 1.8 nM, respectively. DC4SMe can be used for targeted therapy of tumors. DC4SMe is a phosphate prodrug of the cytotoxic DNA alkylating agent DC4 and can be used in the
5'-O-DMT-N4-Ac-dC (N4-Acetyl-2'-deoxy-5'-O-DMT-cytidine, compound 7) is a deoxynucleoside utilized in the synthesis of dodecyl phosphoramidite. Dodecyl phosphoramidite serves as a crucial precursor for dod-DNA production, which is amphiphilic DNA comprising dodecyl phosphotriester linkages and featuring an internal hydrophobic region[1][2].
DC41SMe is a DC1 derivative that is cytotoxic to Ramos, Namalwa and HL60 s with IC50s ranging from 18-25 pM. DC1 is a simplified analogue of CC-1065, an antibody conjugate of cytotoxic DNA alkylation molecules, used for targeted treatment of cancer.
